Description

Technical Field

[0001] This invention relates to the field of connector technology, and more specifically to a floating locking radio frequency connector. Background Technology

[0002] With the miniaturization, integration, and high frequency development of electronic components, especially the increasing requirements for integration, higher demands are being placed on product reliability.

[0003] The increasing performance requirements of RF integrated products and the overall system link requirements, as well as the increasingly demanding application environments, urgently necessitate the development of new products to meet the relevant industry requirements. For RF contacts in integrated modules, it is not only necessary to achieve the transmission of RF signals, but also to allow the RF contacts to float freely within the integrated module in order to meet the requirements of large tolerances in mechanical installation.

[0004] However, existing radio frequency contacts cannot be fixed and locked during floating docking, resulting in unreliable contact in high vibration environments and lower product performance stability after docking. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a floating locking radio frequency connector to solve the problem that the radio frequency contacts in current connectors cannot be fixed and locked during floating docking.

[0006] To solve the above-mentioned technical problems, the present invention is implemented using the following technical solution:

[0007] This invention provides a floating locking radio frequency connector, comprising: a socket connector and a plug connector;

[0008] The socket connector includes a first housing and a pin contact mounted on the first housing. The pin contact includes a first outer conductor, and a limiting groove is formed on the outer wall of the mating end of the first outer conductor.

[0009] The plug connector includes a second housing and a socket contact mounted on the second housing. The socket contact includes a second outer conductor, and the mating end of the second outer conductor has a slot that matches the mating end of the first outer conductor.

[0010] The socket contact also includes a limiting ball. The outer wall of the mating end of the second outer conductor is provided with a plurality of mounting holes that are adapted to the limiting ball. The limiting ball is movably installed in the mounting holes.

[0011] When the socket connector and the plug connector are in the plugged state, the mating end of the first outer conductor is mated with the slot, the limiting groove is aligned with the mounting hole, one side of the limiting ball presses against the second outer shell, and the other side extends into the limiting groove through the mounting hole to achieve axial limiting of the first outer conductor and the second outer conductor.

[0012] Furthermore, the first outer shell has a mating groove at its mating end, and a first through cavity for installing a pin contact is provided in the mating groove. The pin contact also includes a socket assembly installed in the first outer conductor, and the mating end of the first outer conductor is exposed in the mating groove.

[0013] The second housing has a mating end with a plug-in portion that matches the mating groove. The end face of the plug-in portion has a second through cavity for installing a pin contact. The plug contact also includes a pin assembly installed in the second outer conductor.

[0014] The socket contact also includes an elastic clamping component and a limiting sleeve. The mating end of the second outer conductor is provided with a plurality of mounting holes adapted to the limiting ball along the circumferential direction. The limiting ball is movably installed in the mounting holes. The second through cavity includes a moving channel, a squeezing channel, a receiving channel and a guide channel connected in sequence. The elastic clamping component is fitted on the second outer conductor and arranged in the receiving channel. The limiting sleeve is fixedly fitted on the second outer conductor and can slide along the guide channel.

[0015] In the separated state: due to the pushing of the elastic clamping component and the axial limiting of the limiting sleeve, the docking end of the second outer conductor is in the movable channel, and the limiting ball cannot be disengaged from the mounting hole due to the limitation of the movable channel;

[0016] In the plugged state: the mating end of the first outer conductor is mated with the slot, so that the limiting groove is aligned with the mounting hole, and the mating end of the second outer conductor is pushed back from the movable channel to the extrusion channel, so that the extrusion channel laterally extrudes the limiting ball, so that the limiting ball extends into the slot through the mounting hole and remains engaged with the limiting groove.

[0017] Furthermore, the elastic clamping assembly includes a spring, a locking ring, and a sleeve. The spring and the sleeve are both sleeved on the second outer conductor. The spring is supported between the second outer conductor and the sleeve. The locking ring is sleeved on the sleeve and abuts against the bottom wall of the receiving channel.

[0018] Furthermore, the limiting sleeve includes a sleeve fixedly sleeved on the second outer conductor and a blocking ring disposed on the outer circumferential wall of the sleeve. The sleeve can slide along the guide channel, and the blocking ring can abut against the end face of the second outer shell, thereby axially limiting the insertion contact.

[0019] Furthermore, the socket assembly includes a first dielectric body fixedly installed inside the first outer conductor, a socket fitted inside the first dielectric body, and a second dielectric body disposed at the tail end of the socket, wherein the head end of the socket extends into the mating end inside the first outer conductor.

[0020] Furthermore, the pin assembly includes a third dielectric body fixedly installed inside the second outer conductor, a pin fitted inside the third dielectric body, and a fourth dielectric body located at the tail end of the pin, with the tip of the pin extending into the slot.

[0021] Furthermore, multiple spaced linear grooves are provided on the circumferentially distributed end of the first outer conductor, and an annular groove is provided on the circumferential outer wall of the end of the first outer conductor, forming an elastic spring structure.

[0022] Furthermore, the first housing is provided with a first locking component on both sides, and the second housing is provided with a second locking component on both sides; after the socket connector and the plug connector are mated, the first locking component can be mated and locked with the second locking component.

[0023] Furthermore, the first locking assembly includes a mounting screw and a mounting nut, and a first support ring is provided on the side end of the first housing. The mounting screw passes through the first support ring and is threadedly connected to the mounting nut.

[0024] The second locking assembly includes a locking screw and a fixing tube. The second housing has a second support ring on its side end. The second support ring is fixedly sleeved on the fixing tube. The locking screw passes through the fixing tube and can be threadedly connected to the mounting screw.

[0025] Furthermore, the first locking assembly includes a flat washer and a first spring washer, which are sleeved on the screw of the mounting screw and arranged between the mounting nut and the first support ring;

[0026] The fixing tube has a coaxially arranged limiting hole and receiving hole. The limiting hole matches the screw rod of the locking screw, and the receiving hole matches the screw head of the locking screw. The second locking assembly includes a second spring washer, which is sleeved on the screw rod of the locking screw.

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0028] 1. This invention uses a compression channel to laterally compress a limiting ball, allowing the limiting ball to extend into the slot through the mounting hole and engage with the limiting groove. This ensures that the pin contact and the socket contact are fixed and locked during the floating docking process, enabling reliable contact in high-vibration environments. This improves the stability of the product performance after docking, better meets the low phase noise requirements in complex environments, and also enables automatic unlocking of the contacts after the socket connector and plug connector are separated. Its structure is simple and compact, with good practical application results. It solves the problem of high phase noise and significantly improves the performance indicators of the entire link. It can be widely used in communication equipment, weapon systems, instruments and meters and other occasions.

[0029] 2. The locking ring of the present invention uses the bottom wall of the receiving channel for limiting and the sleeve to support the spring, thereby stably realizing axial floating. It is easy to manufacture and assemble and has high structural stability.

[0030] 3. This invention connects and tightens the screw of the locking screw with the threaded hole at the end of the mounting screw, thereby completing the connection and locking of the first locking component and the second locking component. It has the advantages of simple operation, convenient disassembly and assembly, and stable installation, and has good practical application effect. Attached Figure Description

Detailed Implementation

[0041] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0042] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include two or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0043] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0044] like Figures 1-8As shown, this embodiment of the invention provides a floating locking radio frequency connector, including: a socket connector 1 and a plug connector 2. The socket connector 1 includes a first housing 11 and a pin contact 12. The mating end of the first housing 11 has a mating groove 111, and a first through cavity 112 for mounting the pin contact 12 is formed within the mating groove 111. The pin contact 12 includes a first outer conductor 121 and a socket assembly 122 mounted within the first outer conductor 121. The mating end of the first outer conductor 121 is exposed within the mating groove 111 and has a limiting groove 121a on its outer wall. The plug connector 2 includes a second housing 21 and a socket contact 22. The mating end of the second housing 21 has a plug portion 211 that matches the mating groove 111. The end face of the plug portion 211 has a second through cavity 212 for mounting the pin contact 12. The socket contact 22 includes a second outer conductor 221 and a socket assembly 122 mounted within the second outer conductor. The pin assembly 222 inside 221 has a slot 221a at the mating end of the second outer conductor 221 that matches the mating end of the first outer conductor 121; the socket contact 22 also includes a limiting ball 223, an elastic pressing assembly 224 and a limiting sleeve 225. The mating end of the second outer conductor 221 has a plurality of mounting holes 221b that are adapted to the limiting ball 223 along the circumferential direction. The limiting ball 223 is movably installed in the mounting hole 221b. The second cavity 212 includes a movable channel 212a, a pressing channel 212b, a receiving channel 212c and a guide channel 212d connected in sequence. The elastic pressing assembly 224 is fitted on the second outer conductor 221 and arranged in the receiving channel 212c. The limiting sleeve 225 is fixedly fitted on the second outer conductor 221 and can slide along the guide channel 212d.

[0045] In the separated state: by the push of the elastic clamping component 224 and the axial limitation of the limiting sleeve 225, the mating end of the second outer conductor 221 is in the movable channel 212a, and the limiting ball 223 cannot be disengaged from the mounting hole 221b due to the limitation of the movable channel 212a.

[0046] Specifically, the mounting hole 221b is preferably arc-shaped, so as to more closely limit and block the limiting ball 223 and prevent the limiting ball 223 from falling into the moving channel 221a.

[0047] When docking is required, the second housing 21 of the plug connector 2 is first docked with the first housing 11 of the socket connector 1, that is, the plug part 211 is inserted into the docking groove 111. This guides the docking of the pin contact 12 and the socket contact 22, so that the docking end of the first outer conductor 121 can be accurately inserted into the slot 221a, thereby enabling the socket assembly 122 and the pin assembly 222 to complete the docking.

[0048] It is understandable that when the mating end of the second outer conductor 221 is in the active channel 212a, the limiting ball 223 is not subjected to lateral compression, so it can be completely retracted into the mounting hole 221b, thus not interfering with the insertion of the first outer conductor 121 and the second outer conductor 221.

[0049] In the plugged-in state: the mating end of the first outer conductor 121 is mated with the slot 221a, so that the limiting groove 121a is aligned with the mounting hole 221b, and the mating end of the second outer conductor 221 is pushed back from the movable channel 212a to the pressing channel 212b, so that the pressing channel 212b presses the limiting ball 223 laterally, so that the limiting ball 223 extends into the slot 221a through the mounting hole 221b and is engaged with the limiting groove 121a.

[0050] Specifically, the limiting groove 121a is preferably an annular structure, which improves the tolerance of alignment with the mounting hole 221b, enhances the smoothness of locking, and reduces the failure rate.

[0051] It should be noted that when the limiting ball 223 is engaged with the limiting groove 121a, the mating end of the first outer conductor 121 will be locked and fixed in the slot 221a, thereby enabling the socket assembly 122 and the pin assembly 222 to be fixed and locked during the floating docking process, which can complete reliable contact in a high vibration environment and improve the stability of the product performance after docking.

[0052] When separation is required, the second housing 21 of the plug connector 2 is separated from the first housing 11 of the socket connector 1, that is, the plug portion 211 is separated from the mating groove 111, thereby disengaging the pin contact 12 and the socket contact 22, allowing the mating end of the first outer conductor 121 to exit from the slot 221a, thereby separating the socket assembly 122 from the pin assembly 222.

[0053] Understandably, when the pin contact 12 drives the mating end of the socket contact 22 to re-enter the active channel 212a, the limiting ball 223 will no longer be laterally squeezed by the compression channel 212b. Thus, the first outer conductor 121 can push the limiting ball 223 back into the mounting hole 221b, thereby no longer engaging with the limiting groove 121a, and thus no longer axially limiting the first outer conductor 121, allowing the mating end of the first outer conductor 121 to smoothly separate from the slot 221a.

[0054] Through the above settings, the pin contact 12 and the socket contact 22 are fixed and locked during the floating docking process, thereby enabling reliable contact in high vibration environments, improving the stability of product performance after docking, better meeting the low phase noise requirements in complex environments, and also enabling automatic unlocking of the contacts after the socket connector 1 and plug connector 2 are separated. Its structure is simple and compact, with good practical application effect, solving the problem of high phase noise, and significantly improving the performance indicators of the entire link; it can be widely used in communication equipment, weapon systems, instruments and meters and other occasions.

[0055] like Figure 5 As shown, in this embodiment, the elastic clamping assembly 224 includes: a spring 224a, a locking ring 224b, and a sleeve 224c. The spring 224a and the sleeve 224c are both sleeved on the second outer conductor 221. The spring 224a is supported between the second outer conductor 221 and the sleeve 224c. The locking ring 224b is sleeved on the sleeve 224c and abuts against the bottom wall of the receiving channel 212c.

[0056] Specifically, the second outer conductor 221 has a accommodating annular groove on its circumferential outer wall for accommodating the elastic clamping assembly 224, so that one end of the spring 224a abuts against the bottom wall of the accommodating annular groove and the other end abuts against the sleeve 224c. The locking ring 224b, by means of the limiting of the bottom wall of the accommodating channel 212c, supports the spring 224a through the sleeve 224c, which facilitates production and assembly and improves the stability of the elastic clamping.

[0057] like Figure 5 As shown, in this embodiment, the limiting sleeve 225 includes a sleeve 225a fixedly sleeved on the second outer conductor 221 and a blocking ring 225b disposed on the circumferential outer wall of the sleeve 225a. The sleeve 225a can slide along the guide channel 212d, and the blocking ring 225b can abut against the end face of the second outer shell 21, thereby axially limiting the insertion contact 22.

[0058] Specifically, the second outer conductor 221 can slide along the guide channel 212d through the sleeve 225a, which plays a limiting and guiding role, ensuring the smooth floating docking of the socket contact 22. The two can be fixed by riveting during assembly, but not limited to this, and no specific limitation is made.

[0059] like Figure 2 As shown, in this embodiment, the socket assembly 122 includes a first dielectric body 122a fixedly installed in the first outer conductor 121, a socket 122b fitted in the first dielectric body 122a, and a second dielectric body 122c disposed at the tail end of the socket 122b. The head end of the socket 122b extends into the mating end in the first outer conductor 121.

[0060] Specifically, the socket 122b is installed inside the first outer conductor 121 through the first dielectric 122a, thereby obtaining stable support. The second dielectric 122c is used to improve the stability of the socket 122b and the part to be connected, and to prevent it from becoming loose, thereby improving the stability of the socket 122b.

[0061] like Figure 5 As shown, in this embodiment, the pin assembly 222 includes a third dielectric body 222a fixedly installed in the second outer conductor 221, a pin 222b fitted in the third dielectric body 222a, and a fourth dielectric body 222c disposed at the tail end of the pin 222b. The head end of the pin 222b extends into the slot 221a.

[0062] Specifically, the pin 222b is installed inside the second outer conductor 221 through the third dielectric 222a, thereby obtaining stable support. The fourth dielectric 222c is used to improve the stability of the connection between the pin 222b and the component to be connected, and to prevent it from becoming loose, thereby improving the stability of the pin 222b.

[0063] like Figure 2 As shown, in this embodiment, a plurality of linear grooves 121b are provided circumferentially on the mating end of the first outer conductor 121, and an annular groove 121c is provided on the circumferential outer wall of the mating end of the first outer conductor 121, forming an elastic spring structure.

[0064] Specifically, by forming an elastic spring structure, the fault tolerance of the mating end of the first outer conductor 121 and the slot 221a can be improved, which plays a role in limiting and guiding, and improves the smoothness of the mating. Example

[0065] like Figure 1 and Figure 7 As shown, this embodiment provides a floating locking radio frequency connector, which differs from the first embodiment in that the first housing 11 is provided with a first locking component 13 on both sides, and the second housing 21 is provided with a second locking component 23 on both sides; after the socket connector 1 and the plug connector 2 are docked, the first locking component 13 can dock and lock with the second locking component 23.

[0066] Specifically, by mating and locking the first locking component 13 and the second locking component 23, the socket connector 1 and the plug connector 2 can maintain a stable connection, thereby improving the stability of the connector connection.

[0067] In this embodiment, the first locking assembly 13 includes a mounting screw 131 and a mounting nut 132. The side end of the first housing 11 is provided with a first support ring 113. The mounting screw 131 passes through the first support ring 113 and is threadedly connected to the mounting nut 132. The second locking assembly 23 includes a locking screw 231 and a fixing tube 232. The side end of the second housing 21 is provided with a second support ring 213. The second support ring 213 is fixedly sleeved on the fixing tube 232. The locking screw 231 passes through the fixing tube 232 and can be threadedly connected to the mounting screw 131.

[0068] It should be noted that in actual use, the mounting screw 131 is threaded to the mounting nut 132 after passing through the positioning hole and the first support ring 113 on the device to be installed, so that the socket connector 1 can be fixedly installed on the device to be installed. This method has the advantages of simple operation, convenient disassembly and assembly, and stable installation, and the actual application effect is good. The fixing tube 232 is fixedly connected to the second support ring 213 by riveting, which facilitates production assembly.

[0069] After the socket connector 1 and the plug connector 2 are mated, the screw of the locking screw 231 is mated with the threaded hole at the end of the mounting screw 131 and tightened, thereby completing the mating and locking of the first locking assembly 13 and the second locking assembly 23.

[0070] In this embodiment, the first locking assembly 13 includes a flat washer 133 and a first spring washer 134, which are sleeved on the screw of the mounting screw 131 and arranged between the mounting nut 132 and the first support ring 113.

[0071] Specifically, after the mounting nut 132 is tightened, it can cooperate with the first support ring 113 to clamp the mounting nut 132 and the flat washer 133, thereby using the spring force to increase the friction of the mounting nut 132 after tightening, preventing it from loosening during use and improving the performance.

[0072] like Figure 3 As shown, in this embodiment, the fixing tube 232 is provided with a limiting hole 232a and a receiving hole 232b arranged coaxially. The limiting hole 232a matches the screw of the locking screw 231, and the receiving hole 232b matches the screw head of the locking screw 231. The second locking assembly 23 includes a second spring washer 233, which is sleeved on the screw of the locking screw 231.

[0073] Specifically, the limiting hole 232a matches the thread of the locking screw 231, thus serving as a limiting and guiding function to prevent lateral wobbling and improve connection stability. The receiving hole 232b matches the thread head of the locking screw 231, thus serving as an axial limiting function, ensuring that the locking screw 231 remains fixed to the fixing tube 232 after being locked with the mounting screw 131. Its structure is simple and compact, facilitating production and assembly.

[0074] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
